SPECIPECATIQN forming part of Letters Patent No. 325,797, dated September 8,1885.

Application filed February 7, 1885. (No model.)

To all whom it may concern Be it known that I, GEORGE A. FULLERTON, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Machine for Molding Heel-Stiffeners and other Like Articles, of which the following is a specification, reference being had to the accompanying drawings, making a part hereof, in which Figure 1 is a plan of my machine, showing the best form now known to me. Fig. 2 is a side elevation. Fig. 3 is a section on line as w,

' and Fig. 4 on line 3 y, and Fig. 5 on line z 2,

Fig. 1. Fig. 6 is a horizontal section of a part of the machine on line 8 s, Fig. 7. Fig. 7 is an interior View of one of the side frames,

showing the plate d and the plate d, as formed.

with grooves diagonally across its inner end and its arrangement with the pinion g on shaft 12 Fig. 8 is a detail view, showing the side and top of plate (1. f

My machine is designed mainly to mold a flat blank into a shape approximating the shape of a counter when in the shoe, and is on a new principle, which differs radically from that of any other machine known to me for doing this or any like work.

The chief novelty of my machine is the molding-bed, composed of a series of ribs, a, (best seen in Figs. 1, 4, 5, and 6,) which form a bed to receive the. blank and give it its curves crosswise of the blank, asthe blank is first applied, and which move one after the other in a curvedpath, while the blank is held firmly upon and moves with them to complete the -moldingthat is, to curve the blank lengthwise and set the other curves. It is this molding-bed which constitutes the main feature of my invention; and while I have shown in the drawings and fully described below the best means for actuating it, and vfor feeding and holding the blank to it, I do not wish to limit myself to these means, as I have contemplated other means, and am aware that still others may be used. 1

In order to give the desired firmness and strength to each rib a of my molding bed, I make each in one piece with its carrier or, and these carriers I form into an endless chain,

as shown in Fig. 3, and mount upon sprocket-wheels b 1/, (see Fig. 3,) so that when the sprocket -wheels are revolved the chain is moved, as will be clear.

The motion of the carriers a gives alike motion to the ribs a. (See Fig. 4. The guide -plate d and the spring-plate d form the mouth of the machine, and the counterblank is inserted between the plate 01 and guideplate d, with its lower edge on plate d until its forward end is caught by the ribs a, (which are preferably toothed, as shown, in order that they may the better nip the blank,)

f, and as the blank is thus carried under the cam f it is bent over so that it becomes nearly parallelwith the upper surface of the supporting-bed, and this parallelism is increased as it is Thus, when the counter-blank is fed inwith its lower edge upon plate d and with its flangeforming portion between plate (1 and the ribs a, it is carried forward by the motion of ribs and forced close upon the outer surface of the ribs a, and as the ribs a pass around the shaft 1) it is strained and curved lengthwise, and falls, finished, from the under side of the molding-bed.

Instead of using the flat surface of plate at to hold the flange-forming portion of the blank until the blank is pressed between the cam f 2 and the moldingbed, it is desirable to use instead the cylinder 9, toothed as shown, and with its axis inclined to the axis of shaft b*, so that its teeth may mesh with those of the ribs or, as this device seems blank around the curve more perfectly than any other.

The plate d should also be formed with grooves diagonally across its inner end, as shown in Figs. 6, 7, and 8, as these grooves tend to hold the lower edge of the blank down close upon plate d The two sprocket wheel shafts are driven and carried along by the ribs a, until its forward upper edge strikes the deflecting cam to carry the flange-forming portion of the carried under cam f, and completed by cam f a, and also firmly held, while it is deflected by gears h h, which receive motion from gear h, and gear h also meshes with the stud-gear h, which meshes with the gears if h of the 1 other like articles, the molding-bed, above decams f f. Gamf is driven by gear h, which scribed, composed of ribs a, arranged and 0pmeshes with gear If. The cams f f f may crating, substantially as described.

be stationary instead of revolving; but they GEORGE A. FULLERTON. 5 are preferably as shown. I Witnesses:
